Nick Raven - lost in the Amazon

A while ago (here) I looked at a book that, according to most of the comments that were left, most people seemed to reckon was about the best book people ever found in the school library. Copies of the series seem really hard to track down so I was delighted to spot this copy on ebay and swipe the photos from it.

So without further ado here's more examples of Gerry Embleton's art from the "...with Nick Raven and the S.A.T.A.N. Squad" series, this time we're Lost in the Amazon... 

Impressively the story is written by the leader of the Wallace Expedition to Amazonia (1978) - kudos.
